GREASE-CUP.

To all whom it may concern:

Be it known that I, ALBERT A. WVALTZ, a citizen of the United States, residin at Orient, in the county of Franklin and tate 'of Illinois, have invented certain new and providing an oil cup which is constructed in two parts in order to facilitate refilling, and further, isprovided with novel fastening means for securing the two parts together.

Other objects and advantages of the 1nvention will be more readily understood from the following description and drawings wherein I have illustrated the invention in its preferred embodiment and in which drawings Figure 1 is a side elevation of my complete cup.

Fig. 2 is a vertical sectionalvlew of the construction shown in Fig. 1, w th the plunger stem and feed pipe in elevation Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. 2, and

Fig. 4 is a detail view of the fastening means provided for securing the two parts of the cup together.

My improved oil cup comprises a cylindrical body portion or shell 1,wh1ch 1s closed at its upper end as indicated at 2 and is opened at its lower end. Upon the upper closed end 2 is formed a cylindrical dome 3, provided with a spiral slot l extendlng c1rcumferentially and longitudmally thereof. Mounted for sliding movement within the cylinder is a circular plunger disk 5 hav ng notches 6 formed in its periphery to receive guide ribs 7 extending vertically along the sides of the body portion at diametrically opposite points therein. Passing loosely through the central part of this plunger disk is a plunger rod 8, equipped at its lower end with an enlarged head 9 which engages the under surface of the plunger disk and serves to properly support the same upon the rod.

Specification of Letters Patent. .Pajgented N 12,191 8 Application filed May 15, 1918.

Serial N0. 234,697.

This rod extends upwardly through the ranged to embrace the rod 8 between theupper closed end 2 of the cylinder and the upper face of the plunger disk 1, and normally tends to force the plunger toward the lower end of the cylinder.

The lower open end "of the cylindrical-= body portion is closed by a removable cover comprising a concave central portion 12 and an annular fiat portion 15 integral with and surrounding said central portion. Upon the upper face of this flat portion 13'- are formed spaced vertically extending flanges-1a and 15 respectively. These flanges as more clearly shown in Fig. 2 engage opposite. sides of the shell adjacent the lower end thereof,

the extreme lower edge of the shell resting upon the upper face of the portion 1'3' between said flanges. A. feed pipe 16 depend ing from the concave central portion 12 provides for the proper distribution of the oil.v

To hold the removable bottom properly 7 associated therewith, I provide the shell 1 with suitable fasteningfingers adapted 'to be engaged beneath the lower face of the flat portion 13 of said bottom. Each of these fingers comprises a vertical portion 17 having its upper end integrally connected with the body portion by means of a short right angularextension 18. A second angular extension forming a finger 19 is provided at the lower end of the portion 17 and this finger is directed inwardly toward the body portion at a point below the lower edge or end thereof. To assemble the shell and removable bottom the finge'rs 19 are passed downwardly through suitable vertical slots 20 formed in the outer flange 15 and the body portion is then turned with respect to the bottom a sufficient distance to engage the fingers with the under face of the portion 13 to one side of the slots 20. Suitable pivoted latches 21 carried by said flanges 15 are then engaged With the fingers 19 as shown in Fig. 1 in order to prevent the same from accidentally moving into alinement with said slots.

In use, the plunger disk 5 is held in the position shown in Fig. 2 when filling the cup through the open end thereof. The removable bottom is then fastened tothe open end of the cup in the manner previously referred to, and the cup is then ready for use. The automatic feed of the oil is accomplished by means of the spring 11 which exerts a continual pressure upon the plunger disk and gradually drives the same toward the removable bottom 12 thus forcing the oil out through the feed pipe 16. The arm 10 operating in the slot l retards movement of the plunger disk to such an extent that the proper feeding of the oil will be effected and in this connection it Will be noted that the arm 10 also provides a convenient hand piece for retracting the plunger when refilling the cup.

It is to be also understood that 1 have shown my invention merely in its preferred embodiment and 1 therefore reserve the right to change the construction and arrangement of the parts as 1 see fit providing that any such changes contemplated come Within the scope of the appended claims and do not depart from the spirit of the invention.

I claim 1. An oil cup equipped with a spiral slot, a spring pressed plunger movable in said cup, and a rod carried by said plunger, and equipped with an arm operating in said slot to retard action of the spring on the plunger.

2. An oil cup provided with a dome having a spiral slot, a spring pressed plunger movable in said cup, a stem carried by said plunger and passing through said dome, and an arm carried by said stem and operating in. said slot to regulate action of the spring on the plunger.

3. An oil cup having guide ribs extending along its inner face, a dome formed upon the upper end of said cup and provided with a spiral slot, a plunger movable in said cup and notched to receive said ribs, a stem carried by said plunger and passing through said dome, an arm carried by said stem and operatin in said spiral slot, and a spring encircling the stem between said plunger and the top of the oil cup.

l. An oil cup comprising a body portion open at its lower end, a removable bottom closed in said open end, fastening members carried by the body portion to releasably retain the bottom in posit-ion and a spring pressed plunger movable in said body.

5. An oil cup including a cylindrical body open at its lower end, a removable bottom provided with spaced vertical flanges receiving the lower end of said body therebetween, the outer of said flanges having slots formed therein, supporting ringers carried by said body and adapted to be passed through said slots for engagement with the under face of said bottom, and hooks carried by said outer flanges to retain said fingers in locked posi tion to one 01: side of said slots.

In testimony whereof I ailix my signature in presence of two Witnesses.
